DOOR-CHECK.

v SPECIFICATION forming part of Letters Patent No. 364,616, dated June 7, 1887.

A Application filed April 27, 188?. Serial No. 236,2.l1. (No model.)

To all whom it may concern: I

Be it known. that I, HARRY WALKER, a citizen of the United States, residing at Wilmington, in the county of New Castle and State of Delaware, have invented certain new and useful Improvements in Door-Checks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to the class of devices used for holding doors ajar; and it consists,

. essentially, of a lever pivoted to the door and carrying onone of its arms a brake which is adapted to be pressed upon the floor to hold the door by friction in any desired position. In the accompanying drawings, which illustrate my invention and form a part of this showing the brake in and out ofoperation. Fig.

3 represents a section on the line 1 1, Fig. 2..

A designates a base-plate, which is secured to the door near the bottom and preferably near the front edge, as illustrated in Fig. 1. To this base-plate is pivoted a vibrating or swinging lever, B, thelower end of which carries a brake, O, to be pressed upon the floor to hold the door by friction in any desired position. I

The upper end of the lever B is forked, the two branches 1) b standing at approximately right angles to each other in the plane of vibration. The ends of these branches are bent out, so as to be conveniently operated by the foot in applying or releasing the brake.

The brake 0 consists of a wheel journaled to the lower end of the lever B, and is adapted to roll on the floor 'in applying orreleasing the same. her band or tire, c, which is seated in a groove in the periphery, asshown in Fig. 3, and which forms an elastic bearing-surface.

The base-plateA has an outturned flange, a, along a portion of its loweredge, which forms a stop for the lever B. This flange terminates operated conveniently with the foot.

The wheel is provided with a rub-- at a point which allows the lower end of the lever to be turned slightly past the vertical center, as represented in Fig. 2, whereby the brake is retained in posit-ion and is prevented from becoming accidentally unfastened. When the brake is released, the flange a forms a support for one of the arms of the lever, to prevent the same from being turned far enough to strike the floor.

The upper end of the lever B is forked merely for the purpose of enabling it to be Obviously, the operation would be the same if a straight lever were used instead of the forked lever shown and described, and such a lever is therefore to be regarded as falling within the scope of my invention.

The device constructed as shown and described is adapted to be used also as a sashthebrake O, journaled on the lowerend of the lever, the said flange a forming a stop and support for the lever, substantially as shown and described.

2. In a door-check, the combination of a base-plate, A, adapted to be secured to a door and provided with a flange, a, the three-armed .lever B, pivotally connected with said baseplate, anda brake, O, journaled on the lower end of the lever, the said flange a forming a stop and support for the lever, substantially as shown and described.

In testimony whereof I afflx my signature in presence of two witnesses. f
